Densha de GO! is a 1997 train simulator arcade game developed and published by Taito in Japan. Players are tasked with driving a train, adhering to the schedule and obeying signals and speed restrictions. It features real-world train lines from Japan, including the Yamanote Line and Keihin-Tohoku Line. The game was ported to the PC, Sega Saturn, and PlayStation.

The concept for Densha de Go! was inspired by designer Akira Saito's personal fascination with Japanese train lines and railroads. He wanted to create a game that allowed players to familiarize themselves with driving a train. The controls were his primary focus as he wanted them to be accurate and responsive, and to mimic the controls of a real train—his father worked for the Kyoto City Transportation Bureau Facilities Division, which made this easier to accomplish. Saito included real-world railroads and trains to appeal towards other railroad enthusiasts, thinking that it could also attract more "ordinary" players for its realistic, familiar theme. As arcades at the time were dominated primarily by racing and fighting games, he believed its unique concept could make it stand out.

Densha de Go! is among Taito's most successful games, preceded only by Space Invaders. The PlayStation version sold over one million copies. The game was well-received by critics for its controls, attention to detail, and unique concept. Some felt that its home releases lacked enough content and had poor visuals. It was followed by a long series of sequels, spin-offs, and reimaginings, beginning with Densha de Go! 2 in 1999.
